Strong to Severe Storms are Possible This Afternoon and Evening

Share this post

We have been outlined in a Marginal (Level 1/5) Risk for severe thunderstorms this afternoon and evening by the Storm Prediction Center (SPC). A 2/5 Slight Risk has been outlined for northwest Alabama. Damaging winds and a low-end threat of a tornado are possible.

…SUMMARY… Thunderstorms, capable of damaging winds and hail, are expected this afternoon through the early evening across parts of the Mid-Mississippi Valley.
 ...Mid-Mississippi Valley...
   The airmass will be very dry to start the day across the
   Mid-Mississippi Valley, but surface dewpoints will increase rapidly
   through the morning as low-level flow strengthens and brings 60s
   dewpoints northward. This will result in increasing instability by
   mid-afternoon as temperatures increase into the 80s south of the
   decaying overnight convection across the Lower Ohio Valley. A few
   supercells may develop on the southern end of this decaying activity
   during the afternoon. Low-level flow will be relatively weak (<20
   knots), and surface flow quite veered, which may limit a more
   substantial tornado threat. However, strong mid-upper level flow
   should be sufficient for rotating updrafts and the potential for
   large hail and a few damaging wind gusts.

   Later in the evening, more substantial convection is expected to
   develop along the advancing front and quickly become linear. The
   primary threat with this later activity will likely be damaging
   winds and perhaps a brief tornado or two with elongating and curving
   low-level hodographs forecast.
